Today, metal-wound gaskets are now the most widely used gaskets. Their structural density can be made according to different locking force requirements. In order to strengthen the main body and accurately locate, the spiral gasket is internally strengthened. Ring and outer positioning ring, using inner and outer steel rings to control its maximum compression.
The main purpose of the metal wound gasket is that the metal-wound gasket with excellent resilience can automatically adjust the pressure thermal cycle and vibration of the pipeline system, and is especially suitable for uneven load, easy joint relaxation, temperature and pressure periodic changes, In case of shock or vibration. It is a static sealing original for flange joints of valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace.
